A cannonball is shot from a cannon at a launch angle of 63° and an initial velocity of 147 m/s. The gravitational acceleration is -9.8 m/s2. Assuming NO air
resistance, how long will it take the cannonball to reach the peak of its trajectory?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
